analogicmodulation

这里具有一些MATLAB处理图象的源程序，希望对初学者有帮助(here with some MATLAB image of the source, and I hope to help beginners)

This code is to simulate 16-PSK and 16-QAM over AWGN channel

线性调频信号的一种新的频域脉压处理方法,这是一个文章，不怎么好下，在这分享下~~~(Linear FM signal frequency-domain pulse pressure, a new approach, which is a paper, not very good, in that share under ~ ~ ~)

本书由浅入深、循序渐进地介绍了GUI设 计的基础知识和技巧,旨在使读者在较短时间内熟练掌握GUI设计的精要所在(Book Deep, a gradual introduction to the GUI based Account the basic knowledge and skills designed to enable readers to master the essence of GUI design in a relatively short period of time)

三维曲线曲面比较演示系统程序设计 设计一个图形用户界面（GUI）演示常见的三维函数图形，至少包含“三维绘图” 、“选项” 、“退出”等菜单，三维绘图的包括：参数方程x=e-t/20cos(t), y= e-t/20sin(t),z=t其中t 为0到2π、参数方程x=t,y=t2,z=t3其中t为0到1之间（在同一图形界面中分别绘制它们的三维曲面和三维曲线图）。“选项”菜单主要包括：网格开关，图例开关，坐标边框开关，色度空间选择菜单，曲线颜色菜单。(Comparison of three-dimensional curves and surfaces demonstration system design to design a graphical user interface (GUI) presentation function common three-dimensional graphics, at least three-dimensional graphics, options , Exit menu, etc., three-dimensional graphics, including: parameters of equation x = et/20cos (t), y = et/20sin (t), z = t one of t from 0 to 2π, parametric equation x = t, y = t2, z = t3 which t is between 0-1 (in the same graphical interface, respectively, three-dimensional mapping of their surface and three-dimensional curves). Options menu includes: grid switches, legend switches, coordinate frame switch, color space selection menu, menu color curve.)

设计一个按照时间抽取的基2快速傅里叶变换（基2FFT-DIT）。输入倒位序，输出自然顺序。(Design is taken in accordance with the time radix-2 fast Fourier transform the (base 2FFT-DIT). Enter the inversion sequence, the output of the natural order.)

同过matlab来实现数字图像处理中常用的bm3d的去噪方法(Been achieved with digital image processing matlab commonly used bm3d Denoising)

本文利用编写的MATLAB软件结合解析法证，分析了一种新型的接地距离继电器在系统振荡时再发生单相经过渡电阻接地短路时的动作特性。该接地距离继电器的动作判据是通过比较故障后测得的母线电压、补偿电压、零序电流和负序电流四个量的相位关系以确定继电器的动作行为情况 (In this paper, written in MATLAB software analysis and forensic analysis of a new type of ground distance relays in the system oscillation movement characteristics of single-phase transition resistance is shorted to ground. The operating criteria for the ground distance relay bus voltage is measured by comparing the failure, the phase relationship of offset voltage, zero sequence current and negative sequence current four amount to determine the relay actuation behavior )
